Guarded Pallet Lift Description
This guarded pallet lift is a double pillar machine with a Safe Working Load of
1000 Kgs and a lift height of 1410mm. The lifting platform will be big enough to
allow a standard pallet (1200 x 1000mm) to be loaded using a hand pallet truck.
At the upper level, the pallet was unloaded by hand by removing each individual
sack. The guarded pallet lift was constructed from Grade 304 stainless steel and
would be bolted to the floor. Lifting with this guarded pallet lift is accomplished
via chains driven by a motor gearbox mounted at the top of the one column with a
crossover shaft to the other column.
Safety Guard to PD 5304:2005 Safety of Machinery
The safety guard is constructed from 40 x 40 x 3mm stainless steel box section and
2mm stainless steel sheet to meet the requirements of PD 5304:2005 Safety of Machinery.
It would enclose the guarded pallet lift to a height of 3400mm with a hinged door
at each level through which the machine can be loaded and unloaded. Each door is
electrically interlocked to prevent the guarded pallet lift being operated with
a door open and in addition, the doors are mechanically locked closed whilst the
machine is running. Each door may only be opened when the lifting carriage is at
the appropriate level.
Guarded Pallet Lift Application Story
This guarded pallet lift was required to elevate a standard pallet (1200 x 1000mm)
from a ground floor level up to a mezzanine floor at a height of 1410mm. This guarded
pallet lift had a ‘Z’ loading configuration so that the pallet was loaded at the
front and unloaded at the back of the machine at the upper level. This guarded pallet
lift can be mounted on an existing floor and therefore does not require a pit to
be created with the requisite drainage issues.
The pallet being raised was filled with sacks of ingredients that were being loaded
into cooking vessels. The mezzanine floor was too confined to allow the whole pallet
to be removed from the guarded pallet lift so individual pallets were removed by
hand. To assist this, the pallet was raised until the top level of sacks were at
a suitable ergonomic height for removal. Once the first layer had been removed,
the pallet lift could be inched up under ‘dead man’s handle’ control to remove subsequent
layers until the whole pallet was unloaded.
